***apologies for cross-posting***
I’d like to add some information to what Tom Adamich postet on :
We at the German National Library do not have implemented the work level in our bibliographic data yet. During implementing RDA and experimenting with the BIBFRAME model, we do first steps in the direction of work records for bibliographic data.
But we do have entries for works of music in the Integrated Authority File (GND), example: see , modeled with the gnd-ontology .
Further questions and discussion is welcome!
All the best,
